SPECIFICATION forming part of Letters Patent No. 527,928,`da.ted October 23 1894.

i Application filed November 6, 1893. Serial No. 490,127- (No model.)

To a/ZZ whom it may concern:` y a Be it known that I, CHARLES H. BAYLEY, of

Boston, county of Suffolk, State of Massachuseits, have invented an Improvement in Pinking-Machines,0f which the following descripy tion, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Inthe use of pinking machines it is `often necessary to pink edges which are not located at the outer edges of the work, as forinstance,

the edges of a vampA which meet a top, orin-` poses. The devices employed in this instance of my invention to lift the said head and cutter shaft, are a lever and a connected treadle. I have also mounted the bed roll in a novel p manner so that it may be readily adjusted laterally to bring into operative position a fresh portion of the said roll, as desired.

Figure l, in perspective shows a pinking machine embodying m'y invention. Fig. 2 is a sectional detail thereof, together with the treadle, on a smaller scale; and Fig. .3 is a detail to the right of the section line fr, Fig. 2. The frame-work consistsessentially of a base A, having an upright post A', and an arm A2 having a hub A3. The hub A3 receives the screw threaded shank B of a guide- Way B, said shank, preferably at a point bea 10W the hub, being surrounded by a nut B2,

the rotation of which effects the vertical adjustment of the said guideway, a pin B4 extended from the shank and entering a slot in the hub preventing the rotation ofthe shank. The guideway B is grooved for the reception of the foot c of a carriage C having bearings j for the shaft or journals C of the bed roll O2,

preferably of hard rubber, raw-hide, Wood or other usual material used to support leather,

cloth, dre., to be pinked. The carriage has in one of its bearings a positioning pin c3, the

`by the operator, the adjustment of thc carriage cn the guideway enabling a fresh portion of the bed roll to be brought under the t cutter, to be described.

The hollow post A receives the shank CZ of the headD in which the cutter shaft D' has its bearings, said shaft having at one end a rotary pinking cutter cl,`and at its other end a pinion d2 which is engaged by a pinion di on a power shaft d'herein shown as driven by a handle d5, but it will be understood that` the said shaft may be driven by pulleys and by mechanical power if desired. The shank 'l d is surrounded by a spiral spring e, 011e end of which rests on a spring adjusting device.

the effective strength of said spring to be adapted to the requirements of the work nnder the cutter. The lower en d of the shank d has co-operating with it a head-lifting device, shown as a lever f mounted on a rocking pinf, said lever having jointed to it a` suitable treadle f2, shown only below Fig. 2, which treadle is located at or near thefloor `so as to be accessible to the foot of the operator, thus enabling the operator by his or her foot,-both hands being used to control the work,to lift the head and with it the cutter, away from the bed roll, so as to put the work in just the desired position, or to start or stop the cut at the desired point.

1e', shown as a nut applied to athreaded part` t `of the shank, rotation of said nut enabling The head has an edge guide g, the end of p l prefer to use the hand lever h pivoted at h.

The hole m in the post A enables the operator to use a screw driver to loosen the set screw m', and thereafter the adj Listing device e may be easily rotated on the shank d.

IOO

This invention is not limited to the exact shape shown for the guideway and laterally movable carriage, nor to the exact shape shown for the devices intermedate the treadle and the head carrying the cutter shaft, and it will be obvious that the shape of these connecting devices might be variously modified by the exercise of only the ordinary skill of a mechanic, and without the exercise of invention.

Having described my invention, what` I claim, and desire to secure by Letters Patent, 1s-

l. In a pinking machine, a pinking cutter, its shaft, a supporting-head for such shaft, a shank extending from said head at right angles to said shaft and rigidly connected with the said head, a guide in or with relation to which said shank may slide and thereby impart only a vertical movement to such head in a right line, and means for raising and lowering said head and its appurtenances bodily, combined with a bed-roll having its acting face arranged in a plane parallel to the cutter shaft, the parallelism of the bed-roll and the cutter being maintained in all Working positions of these parts and a plane of clear space extending around the cutter and bed-roll and beneath the cutter-shaft, whereby the cutter may be presented at right angles to the Work and the work moved as exigencies require, substantially as described.

2. In a pinking machine, apinking cutter, its shaft, a supporting-head for such shaft, a shank extending from said head at right angles to said shaft and rigidly connected with the said head, a guide in or with relation to which said shank may slide and thereby im part only a vertical movement to such head in a right line, and means for raising and lowering said head and its appurtenances bodily, combined with a bed-roll, a laterally movable carriage in which said bed-roll is supported, the said bed-roll having its acting face arranged in a plane parallel to the cutter-shaft, the parallelism of the bed-roll and the cutter being maintained in all working positions of these parts, and a plane clear space extending around the cutter and bedroll and beneath the cutter-shaft, whereby the cutter may be presented at right angles to the work and the work moved as exigencies require, substantially as described.

3. In a pinking machine, the following instrumentalities, viz:-a bed roll; avertically movable head, a shank depending from said head, an adjustable nuton said shank, a post in which the shank is arranged and a spring interposed between the post and the nut on the shank normally to depress the head; a rotary cutter shaft carried thereby; a pinking cutter, and a treadle and intermediate devices to lift the said head and cutter away from the bed roll, substantially as described.

4. The bed roll, the post A', the head D having a shank d extended loosely in said head, the cutter shaft, its attached pinking cutter,andthe springsurroundingsaid shank, and the spring adjusting device, combined with a treadle and intermediate devices to act on said shank and lift the said head, a device for restraining the head from rotation, and an independent head lifting device which is capable also of holding the head in its raised position substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

CHARLES H. BAYLEY.
